Title: Assembly of image intensifying tubes - uses centring ring and collar joint to spread load and prevent optical distortion
Inventor: BEAUVAIS YVES
IPC: F16L23/04
Filed: 1975-06-24
Abstract: The joint is used to join two cathode tubes (1, 2) forming part of an image intensifying device. Each tube has an entry window (11, 21) and an exit window (12, 22), which carry optical fibres. The two tubes are held on a common axis by the centre ring (7). Two rings of L-shaped cross-section (3, 4) are glued or soldered to the tubes (1, 2). These L-shaped rings (3, 4) are joined by a flexible ring (5) which is glued or soldered. The flexible ring (5) may be of wire mesh or metallic membrane. It is secured by a fixing collar (6) which is fitted with locking screws. This method of joining spreads the load evenly and prevents optical distortion of the image.

Title: Aircraft total energy control system - has aerodynamic and selected climb or inclination modulated with respect to deviations in velocity
IPC: G05D1/06
Filed: 1975-07-04
Abstract: A total energy control system for take off and control system of an aeroplane, controls the aerodynamic inclination (gamma a) to a selected value of inclination or climb (gamma d). This itself represents the total inclination or climb (gamma t) being modulated by the deviation of the velocity (V) from the required velocity (V2). A warning or display signal (delta) is passed between the aerodynamic inclination (gamma a) and the selected inclination (gamma d) by means of a notched positional beam (2) or by means of a Lectz horizon (3).

Title: Metal oxide semiconductor prodn. - by introducing boron ions into oxide film and tempering to adjust silicon substrate surface potential
Inventor: BLACHMAN ARTHUR G
IPC: H01L21/283
Filed: 1975-07-01
Abstract: In the prodn. of metal oxide semiconductors (MOS structures) by applying a SiO2 layer to a p-conducting Si substrate and then adjusting the surface potential of the Si, a negative charge is produced in the boundary layer between then Si substrate and the SiO2 layer by introducing B ions into the SiO2 layer, which makes the substrate surface more strongly p-conducting, and then the oxide-coated substrate is tempered in a gas atmos. Method is useful in the prodn. of MOS capacitors, field effect transistors (FETs) and printed circuit contg. FETs. The process is simple, easy and exact, prevents the formation of positive charges in the SiO2 layer and makes the substrate surface more strongly p-conducting.

Title: Reciprocating driving mechanism for rotating shaft - has two freewheels and differential gear to generate reciprocating motion
IPC: F16H37/14
Filed: 1976-04-21
Abstract: The mechanism transmits a reciprocating movement to a driving shaft. The first positioned free wheel is mounted on the shaft will drive a second shaft in the same direction of rotation as the first. A second free wheel is introduced between a fixed element and the output shaft prevents the shaft from rotating in the opposite direction. This is achieved with the aid of a differential gear which has one side connected to the output shaft and the other to a hydraulic jack. The third side of the differential is connected to the input shaft by means of a friction clutch.

Title: Extendable ladder locking hinge of two-fulcrum type - joints extension to base ladder obtaining complete retraction and angular variation
IPC: B66B9/187
Filed: 1976-09-20
Abstract: The bi-fulcrum (5) lockable-hinge is for use between sections (2, 3) of extendable ladders, and on hoist-ladders in building construction. Use of the hinge permits the extension ladder (3) to be pivoted into a retracted position parallel to and against the base ladder (2), and allows the angular relationship between the two ladder (2, 3) sections to be varied over a wide range. The two ladder-sections may be joined by a hinge piece of two symmetrical trapezoidal plates (4) welded to the insides of the legs of a 'U' shaped rectangular hollow section brace (13). The bar of the 'U' lies parallel with and below the rungs (9) and may have pulley wheels for the hoist. A stub-axle (5) projects internally from each top corner of each plate (4) to enter sleeve pieces (7) which are bolted to the ladders.
Patent FR-2327079-A1 (FR)
Inventor: SCHELKMANN WILHELM
IPC: B29D30/58
Filed: 1976-10-08
Abstract: In the process a rubber tread strip (1), which has on its inner side a bondable rough surface produced in a press mould during the production thereof, is applied onto a carcass (8) covered with a bonding rubber layer (9). The depressions in the rough surface form a network of paths through which any gaseous inclusions can escape during an application of subatmospheric pressure and/or pressing out by means of mechanical pressure exerted on the tread strip (1). After the pressure exertion, the lateral outlet openings are sealed. The blank thus prepared is vulcanised in an autoclave. In the case of relatively large tyres, tread bars or segments can also be used to form the tread. The blank can be prepared in a simple manner without recovering which was hitherto conventional and can be heated in an autoclave.
